(Received 10 July 2012; accepted 11 July 2012; online 18 July 2012)

The asymmetric unit of the title compound, C7H6F2N2S, consists of two independent mol­ecules, with comparable geometries. In one mol­ecule, the thio­urea moiety is essentially planar (r.m.s. deviation = 0.014 Å) and it forms a dihedral angle of 78.67 (9)° with the benzene ring. The corresponding r.m.s. deviation and dihedral angle for the other mol­ecule are 0.011 Å and 81.71 (8)°, respectively. In both mol­ecules, one of the F atoms is disordered over two positions with refined site occupancies of 0.572 (3):0.428 (3) and 0.909 (2):0.091 (2), respectively. In the crystal, mol­ecules are linked via N—H⋯S and C—H⋯F hydrogen bonds into two-dimensional networks parallel to (010).

Comment top

In continuation of our work on the synthesis of thiourea derivatives (Fun et al., 2012a, 2012b; Sarojini et al., 2007), the title compound is prepared and its crystal structure is reported here.

The asymmetric unit (Fig. 1) of the title compound consists of two independent molecules (A and B), with comparable geometries. In molecule A, thiourea moiety (S1A/N1A/N2A/C7A) is essentially planar (r.m.s. deviation = 0.014 Å) and it forms a dihedral angle of 78.67 (9)° with the benzene ring (C1A-C6A). The corresponding r.m.s. deviation and dihedral angle for molecule B are 0.011 Å and 81.71 (8)°, respectively. Bond lengths (Allen et al., 1987) and angles are within normal ranges and are comparable to related structures (Fun et al., 2012a, 2012b). The fluorine atoms (F1A/F1B) of both molecules are disordered over two positions with refined site-occupancies of 0.572 (3):0.428 (3) and 0.909 (2): 0.091 (2), respectively.

In the crystal structure, Fig. 2, molecules are linked via intermolecular N—H···S and C—H···F hydrogen bonds (Table 1) into two-dimensional networks parallel to (010).

Experimental top

2,4-Difluoroaniline (0.84 mL, 0.0081 mol) was refluxed with potassium thiocyanate (1.4 g, 0.0142 mol) in 20 mL of water and 1.6 mL of concentrated HCl for 3 h. The reaction mixture was then cooled to room temperature and stirred overnight. The precipitated product was then filetred, washed with water, dried and recrystallised from acetone and toluene (1:1) mixture by slow evaporation method (m.p. 441-443K).

Refinement top

N-bound hydrogen atoms were located in a difference Fourier map and refined freely with N–H = 0.79 (2)–0.88 (2) Å. The remaining H atoms were positioned geometrically and refined using a riding model with C–H = 0.95 Å and Uiso(H) = 1.2 Ueq(C). The fluorine atoms (F1A/F1B) of both molecules are disordered over two positions with refined site-occupancies of 0.572 (3):0.428 (3) and 0.909 (2): 0.091 (2), respectively. The same Uij parameters were used for atom pair F1B/F1BX.

Structure description top

In continuation of our work on the synthesis of thiourea derivatives (Fun et al., 2012a, 2012b; Sarojini et al., 2007), the title compound is prepared and its crystal structure is reported here.

The asymmetric unit (Fig. 1) of the title compound consists of two independent molecules (A and B), with comparable geometries. In molecule A, thiourea moiety (S1A/N1A/N2A/C7A) is essentially planar (r.m.s. deviation = 0.014 Å) and it forms a dihedral angle of 78.67 (9)° with the benzene ring (C1A-C6A). The corresponding r.m.s. deviation and dihedral angle for molecule B are 0.011 Å and 81.71 (8)°, respectively. Bond lengths (Allen et al., 1987) and angles are within normal ranges and are comparable to related structures (Fun et al., 2012a, 2012b). The fluorine atoms (F1A/F1B) of both molecules are disordered over two positions with refined site-occupancies of 0.572 (3):0.428 (3) and 0.909 (2): 0.091 (2), respectively.

In the crystal structure, Fig. 2, molecules are linked via intermolecular N—H···S and C—H···F hydrogen bonds (Table 1) into two-dimensional networks parallel to (010).

Special details top

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
